WEATHERPROOFING STRUCTURE FOR DOORS 7 Filed May 29, 1950 Da 2/z'a H Ha 777/95 Patented Apr. 18, 1933 P TEN OFFICE DAVID n. HARNLY, or CHICAGO, ILLINOIS wEA'rHER-Pnoorme s'rnucrrnnn ron noons,

. Application filed May 29,

This invention relates in general to a Weather-proofing structure, and more particularly to means for effecting a positive closure of the juncture between a door and its frame or a similar structure, in order to more effectively prevent the passage of dust, rain, snow, and cold air through said juncture.

The invention comprises the novel structure and combination of parts hereinafter described and more particularly pointed out and defined in the appended claims.

In the accompanying drawing, which illustrates a preferred embodiment of this invention and in which similar reference numerals refer to similar features in the different views:

Figure 1 is an elevational view of a door embodying the features of this invention;

Figure 2 is a view in section showing the details of the weather-proofing structure as provided at the lintel and threshold of the door, taken substantially on line 11-11 of Figure 1;

Figure 3 is a transverse, sectional view showing the details of the weather-proofing structure provided for the vertical joint between the door and casing, taken substantially on line III-III of Figure 2;

Figure 4 is a fragmentary sectional view showing the relative position of the joint closing members when the door is in a partially closed position.

As shown on the drawing As illustrative of this invention, there is shown in Figure 1 a door structure embracing a door frame which defines an opening in a 'wall 1. This frame is composed of upright side members or jambs 2 connected by a lintel 3 at the top thereof. A threshold A is secured between the lower ends of the jambsl A stop strip 5 of the usual type is secured to the inner surface of the jambs and lintel, said strip being set back from the forward edge thereof and serving as a stop for the closure 7 member, which is generally indicated by the numeral 6. The closure member or door comprises a top portion 7 and a bottom portion 8 which are connected together by side members which form a lock stile 9 and hanging stile 10. The door is swingably secured 1930. Serial no} {156,887.

to one of the j ambs by means of conventional hinges 11. A central panel 12 is secured at its periphery to the stiles and upperand lower portions, and forms the central portion of the door. j A weather-strip is provided by clamping a strip of material 12*, such as sponge rubber or thelike, in a U-shaped sheath 13 having va bead along one edge of a leg thereof, in

order that the strip will be more firmly gripped thereby. V The weather-strip 'so formed is nailed or otherwise secured to the inner. surface of the 'stop' strip 5 in such a manner-that an edge thereof will project past the forward edge of the stop strip. A marginal groove 14 is provided on the rear or) inner side of the lock stile and the top rail, which extends the entire length thereof. The outer Wall 15 of this groove is at right angles to the bottom thereof, as shown in Figure 4, and the inner wall 16 slopes inwardly and towards the center line of the door, thereby, formingv a groove which is wider at the topthan at the bottom. The

hanging stile 10 is provided'with a rabbet 17 forming a groove on the rear or inner side thereof, said rabbet having a beveled inner wall 18 which slopes inwardly and toward the centerline of the door. Molding strips 19'are secured adjacent the beveled walls of the grooves 14 and the rabbet 17. These molding strips .are provided with a beveled surfaceQO' which forms a continuation of the beveled wallsl'o and18, and also serve to protect the weather-strip when the door is in the closed position. I I

--The lower portion of the door including the stiles is also rabbeted as indicatedatQl, and a weather-strip 12 issecured therein for sealing the doorwith respect to the threshold plate. As thus secured,the weather-strip 12? will project below thef'lower edge of. the door and make contact with theupper surface of the thresholdboard when the door is closed. As the door approaches the completely' closed position the proj ecting portion ofthe weather strip, which is secured to'th'e stop strip, will first contact the beveled surface 20'of the moldingv 19, as shown in Figure 4.- *Upon'the furthermovement to the fully closed position, the weather-strip will slide along this beveled surface and enter the grooves 14 with a wedging action. In the case of the rabbet 17, the beveled surface formed by the surface 20 and the wall 18 will force the weather-strip to completely fill the space between the rabbet and the stop strip adjacent thereto. These beveled surfaces not only guide the weather-strips into the groove and rabbet, but they also compress the same and provide a good seal. This invention, therefore, provides an improved weatherproofing structure for doors and closures of similar nature, which has a large surface contact between the joint closing members, the contact pressure between said members increasing as the closure reaches the fully closed position, thereby more effectively preventing the passage of dust, rain, snow, and cold air through the joint or space between the closure and the frame structure.

I am aware that numerous details of construction may be varied through a wide range without departing from the spirit of this in-. vention, and I, therefore, do not purpose limiting the patent granted otherwise than is necessitated by the prior art.

I claim as my invention:

1. The combination with a door frame, of a continuous weather-strip along the sides and one end thereof, and a door hingedly mounted on said frame having a marginal groove on the rear face of the door for receiving said weather-strip, said groove having 1 a sloping wall for guiding and deflecting said weather-strip thereinto.

2. The combination with a door frame, of a continuous weather-strip secured thereto, a door mounted on said frame having a mar ginal groove for receiving said weather-strip, and a moulding secured adj acent said groove having a sloping surface for guiding and deflecting said weather-strip into said groove.

3. The combination with a door frame, of a Weather-strip secured thereto, a. door secured to said frame having marginal grooves for receiving said weather-strip, said grooves having a sloping wall, and a moulding secured adjacent the outer edge of said wall having a sloping surface lying in the same plane and forming a continuation of said wall, whereby said strip is guided into the groove and transversely compressed against the Wall of the groove.

4. The combination with a door frame, of a weather-strip secured thereto, a door mounted on said frame having grooves for recelvlng said weather-strip, and a moulding secured to said door adjacent said grooves for guiding the weather-strip into the grooves and for extending over said weather-strip and protecting the same when the door is in the closed position.

5. In combination, a door frame, a strip of rubber material secured to said frame, a door mounted in said frame having a beveled groove for receiving said strip, said strip having a thickness greater than the bottom width of said groove, said strip being compressed in the groove when the door is closed.

6. The combination with a door frame, of a Weather-strip secured thereto, a door mounted on said frame having a marginal groove on its rear face for receiving the strip edgewise therein, said strip being of a thickness greater than the bottom of the groove, the groove having a sloping side wall for causing the strip to be compressed within the groove when the door is closed and release the compression as the door is opened.

In testimony whereof I have hereunto subscribed my name at Chicago, Cook County,

Illinois.
